Later on, when I will have time / will get inspired, I will write a general outline of my heavily modified keyboard layout, with a couple additional modifier keys, a couple of remapped keys, and how it al plays nicely with the i3 windows manager.

Up next, sometime, I should do a right-hand version. A bit less useful (still have to learn to eat with my left hand), but much more flexible in terms of functionality. I can reach much more keys with my right hand.
